Best Product – New Diablo Oscillating Multi-Tool Blades

Diablo Oscillating Multi-Tool Cutting Blades

Diablo has come out with new… oscillating multi-tool blades?!

We know that Diablo (and Freud) are part of Bosch Tools, and so is Dremel. As I am sure most of you have seen, Bosch and Dremel both offer a wide range of oscillating multi-tools and accessories.


Diablo also seems to be expanding their selection of power tool accessories (they also came out with step drill bits last year), and while oscillating multi-tool blades might be a new category for Diablo Tools, there’s plenty of know-how ingrained in their parent company.

We have also observed that Diablo offerings has started replacing select Bosch power tool accessories at Home Depot.

I find myself surprised to see new Diablo oscillating multi-tool blades, but given the history and offering of Diablo’s sibling companies, is this really all that surprising?

Diablo’s new universal-style interface looks a lot like Dremel’s older universal-style oscillating multi-tool blades, doesn’t it? The interfaces are hugely similar even nearly identical in appearance.

Dremel seems to have moved to a simpler tool interface style that is said to be compatible with Bosch, Makita, Milwaukee, and Rockwell oscillating multi-tools.

Diablo says their universal-fit oscillating multi-tool blades are compatible with most tools, with no adapters neededHowever, these Diablo universal oscillating multi-tool blades are NOT compatible with the more recent Starlock accessory interface co-designed and launched by Bosch and Fein in recent years.

Diablo Oscillating Multi-Tool Blades

So far, Diablo has released a number of individual blade packs and assortments, including a 5pc universal-fit general purpose oscillating blade set, DOU5S, that should be popular for users looking to try things out.

The 5pc set comes with:

  • 2″ Bi-Metal Blade for Drywall (DOU200RBD)
  • 1-1/4″ Bi-Metal Blade for Nail-Embedded Wood (DOU125BW)
  • 1-1/4″ Carbide Blade for Metal (DOU125CF)
  • 1-1/4″ Carbide Blade for General Purpose Cuts (DOU125CGP)
  • 1-1/4″ Bi-Metal Blade for Clean Wood (DOU125JBW)

Diablo Starlock Oscillating Multi-Tool Blades

If you want Starlock-compatible Diablo oscillating multi-tool blades, well, they have that too – model DOS5S for this 5pc assortment.

That’s right, Diablo Tools will have two separate lines of oscillating multi-tool blades, one with a universal-style interface, and another with a Starlock interface.

Starlock blades are also somewhat universal-fit in nature, capable of fitting a wide range of oscillating multi-tools in addition to Starlock-compatible tools. But, many oscillating multi-tools have tool-free blade change interfaces that only work with open-slot oscillating multi-tool blades.

Bosch Starlock Oscillating Multi-Tool Blade Set

Price-wise, Diablo’s 5pc Starlock blade assortment is on-par with the $50 5pc Starlock-compatible blade assortment offered by Bosch.

From what I can tell thus far, it looks like Diablo Tools, with these two separate oscillating multi-tool blade lineups, can probably fit any modern oscillating multi-tool interface.

Diablo has not sent out any press releases or announcements about this massive accessory launch, but we’ve asked for more information and will update this post if we learn anything new or if there are any notable incompatibilities.

Diablo Universal and Starlock Oscillating Multi-Tool Accessories Examples

And if you think that’s all, well, it’s not. This is a BIG launch.

Diablo Oscillating Multi-Tool Blade Categories

Diablo looks to have gone all-in with their oscillating multi-tool accessories, offering both universal and Starlock-compatible accessories in a wide range of cutting, sanding, and scraping styles.

Here’s a look at the new Diablo oscillating multi-tool blade styles the lineups include at this time:

Diablo Oscillating Multi Tool Blades for Cutting Wood

Diablo Oscillating Multi-Tool Blades for Cutting Wood and Nail-Embedded Wood

There will be bi-metal blades for cutting clean wood and nail-embedded wood with 1-1/4″ and 2-1/2″ curved edges.

Diablo Oscillating Multi Tool Blades for General Purpose Cutting

Diablo Oscillating Multi-Tool Blades for General Purpose Cutting

Diablo’s general purpose OMT blades will be available with carbide and bi-metal teeth, depending on the style.

Carbide-edged OMT blades are vastly longer-lasting than bi-metal, especially when cutting metallic materials such as nails or screws.

Diablo Oscillating Multi Tool Blades for Cutting Metal

Diablo Oscillating Multi-Tool Blades for Metal Cutting

There will be metal-cutting blades in 1-1/4″ width, with bi-metal or carbide teeth.

At this time, it seems that the focus will be on carbide teeth, with bi-metal selection a little more limited. Diablo shows a universal interface blade available with carbide or bi-metal teeth, while the Starlock blade is only available with carbide teeth.

The selection could broaden in the future – remember, this is perhaps only the start of Diablo’s OMT offerings.

Diablo Oscillating Multi Tool Blades for Cutting Drywall

Diablo Oscillating Multi-Tool Blades for Drywall Cutting

There will be a 2″ curved-edge bi-metal blade for cutting drywall.

Diablo Oscillating Multi Tool Sanding Accessories

Of course, what would be an OMT accessory lineup without a sanding pad?

Diablo Oscillating Multi Tool Blades for Grout

Diablo Oscillating Multi-Tool Blades for Grout

There will be carbide and diamond grit accessories for grout removal.

Diablo Oscillating Multi Tool Blades for Scraping

Diablo Oscillating Multi-Tool Blades for Scraping with Universal and Starlock Interfaces

There will be flexible and rigid scraping blades.

Diablo Oscillating Multi Tool Blade Sets

Diablo Oscillating Multi-Tool Blade Sets

As shown earlier in the post, there will be 5pc accessory sets, and also a 3pc set for both interface styles.


The 5pc sets are currently priced at $50, but let’s look at individual blade pricing.

I think the 1-1/4″ general purpose blades might be a good benchmark.

Price Comparison with Bosch Starlock Blades

Bosch OSL114C 3-Pack OMT Cutting Blades Starlock

You can buy a 3-pack of Bosch blades (OSL114C) for $33.11 via Amazon, plus there’s a current “save 20% on 2 select items” promo.

This might not be the fairest comparison, Since Diablo’s blades have a curved contact edge. Diablo doesn’t seem to be launching a straight-edged carbide-toothed OMT blade at this time.

Diablo vs Bosch Oscillating Multi-Tool Blade Comparison

From left to right: Diablo general purpose carbide-toothed blade with curved contact edge, Bosch general purpose carbide-toothed blade, and Bosch “Curved-Tec” carbide-toothed blade.

The Bosch curved contact edge blade, OSL114CC, is ~$24 for one via Amazon, or $28 for two via Amazon.

Diablo’s pricing comes in slightly under, at $39 for three.

Acme Tools has better individual pricing on the Bosch – $16 for one blade – but worse on the Diablo – $45 for three blades.


At this time, until we learn more from Diablo Tools, it would be fair to presume that the new Diablo Starlock-compatible blades might be comparable to Bosch’s. The Diablo accessories have a “Black Ice Coating,” and similar blades have cutting depth markings with greater resolution and with both inch and metric lines.

This isn’t just a “lick and stick” relabeling, where Bosch blades are simply Diablo-branded, with the Diablo blades looking to offer at least some differences even if minor ones.

Are the Diablo universal-style and Starlock-compatible blades of the same quality? Despite Diablo universal OMT blades looking to have an older Dremel-style interface, subtle differences suggest they’re made with different tooling.

Plus, from a brand reputation standpoint, I would assume for the Diablo Tools accessories to be a higher quality grade than Dremel’s.

Diablo has surprised us in multiple ways. First, why launch an oscillating multi-tool accessory lineup now? Does this have something to do with Milwaukee Tool acquiring Imperial Tool, an oscillating multi-tool blade maker?

Milwaukee Tool has recently launched new oscillating multi-tool blades, and it seems more than coincidental for Diablo to get in the game. Is Diablo seen as a stronger competitor against new Milwaukee Tool oscillating multi-tool accessories than Bosch?

But also, don’t forget that Diablo accessories have been replacing Bosch power tool accessories at Home Depot.

These new lines of Diablo oscillating multi-tool accessories seems to be big news, but also a piece of the larger picture. Diablo is breaking out of their comfort zone.

I’m sure these new blades will offer the performance and quality we have come to expect from Diablo Tools accessories, but would hope to see more aggressive pricing compared to Bosch’s offerings.

It seems likely that identical or very similar Diablo and Bosch accessories are made at the same factory, and perhaps even on the same equipment. Users who share in this assumption would be wise to shop according to price and availability.

This is a big launch for Diablo Tools, and gives rise to one big question – what comes next? If this is part of a larger strategy, we’re surely in for more surprises.

Thank you to Cody for the heads-up!
